Definitions

  • My present invention relates to electrodes for electric (primary or secondary) batteries adapted to be used, for example, in an alkaline silver-and-zinc battery of the type disclosed in U. S. Patent No. 2,594,709.
  • a sheet of pliable electrode material adapted to be folded around a set of wires (preferably of silver) which are spread like fingers in different directions, beginning at a point of mutual contact, thereby forming a spider-like network or Web encompassing substantially all of the inner sheet surface in contact with said network.
  • the sheet which may consist of zinc, is preferably perforated to increase its efiective surface and to insure adequate penetration by the electrolyte. Pressure exerted upon the relatively soft sheet portions folded around the relatively hard wires causes the latter to become partially imbedded in the enfolding zinc.
  • Fig. 1 is a view of an electrode according to the invention prior to folding of its sheet
  • Fig. 2 is a side view of the finished electrode
  • Fig. 3 is an end view of the electrode of Fig. 2.
  • the sheet 10, Fig. 1 may be a thin zinc plate and is provided with perforations 11 for the purpose described.
  • a set of wires 12, five of which have been shown by way of example, are spread out like the fingers of a hand to form a current-distributing network encompassing most of the right-hand half of the surface of sheet in Fig. 1; these wires project upwardly beyond the sheet 10 and their upper extremities, which if desired may be twisted together and may be introduced into a protective tube or sheath (not shown), are designed to be connected to the terminal of a battery of which the electrode may form part.
  • Figs. 2 and 3 show how the sheet 10, having been folded around the wires 12, completely encloses the spider-like network or web formed by the lower portions of the wires.
  • the perforations 11 of the two folded halves of the sheet are shown to register with one another, although this is not absolutely necessary.
  • a battery electrode composed of a folded-over sheet of zinc, a network of silver conductor wires encased within the folded-over sheet, said wires radiating from a point on the sheet periphery and across the folded-over sheet to other peripheral points, said zinc sheet being relatively thinner and softer than said silver wires, the portions of said zinc sheet contiguous with the encased silver wires having ridges that embrace the silver wires and form therewith a self-supporting electrode structure with good electrical conductivity.
